INSPECTION PROCEDURE

NOTICE:

When replacing the brake actuator assembly, perform zero point calibration (Click here).

1. Check if the CAN communication system DTC is output (Click here for LHD, or Click here for RHD).
   
   

   Result:

   
   

   Condition	Proceed to
   DTC is not output	A
   DTC is output	B

1. Turn the engine switch on (IG).
   

2. Measure the voltage according to the value(s) in the table below.
   

   Standard voltage:

   Tester Connection	Condition	Specified Condition
   J21-13 (TC) - J21-4 (CG)	Engine switch on (IG)	10 to 14 V

1. Turn the engine switch off.
   

2. Disconnect the ECM connector.
   

3. Measure the resistance according to the value(s) in the table below.
   

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   J21-13 (TC) - A6-3 (TC)	Always	Below 1 Ω
   J21-13 (TC) - Body ground	Always	10 kΩ or higher

1. Measure the resistance according to the value(s) in the table below.
   

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   J21-4 (CG) - Body ground	Always	Below 1 Ω

1. Reconnect the ECM connector.
   

2. Using SST, connect terminals TC and CG of the DLC3.
   

3. Turn the engine switch on (IG).
   

4. Check that the engine warning light is blinking.
   
   

   Result:

   
   

   Condition	Proceed to
   Engine warning light is blinking	A
